At 0.85000 inches nominal size, this block conforms to NIST standards and ships with NIST certification documentation. Grade AS-1 specifies tightly controlled dimensional tolerances appropriate for tool room and inspection use. Machinists, metrologists, and quality technicians rely on gage blocks like this one to verify measuring instruments, set comparators, and establish reference dimensions during production.\u003c\/p\u003e\n\u003cp\u003eThis gage block suits tool room, inspection department, and shop floor applications where a single, certified reference block is needed. It is appropriate for use in dimensional verification setups, surface plate work, and calibration of measuring instruments including micrometers and dial indicators. The NIST certification makes it suitable for quality systems that require traceable measurement standards. Sold individually, this block is a practical addition to an existing gage block set or a standalone reference for a specific dimension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade AS-1 accuracy meets ASME B89.1.9 tool room tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eNIST certification provides traceable measurement documentation\u003c\/li\u003e\n  \u003cli\u003eSteel construction offers durability and resistance to wear under repeated use\u003c\/li\u003e\n  \u003cli\u003eNominal size of 0.85000 inches enables precise single-dimension reference setups\u003c\/li\u003e\n  \u003cli\u003eRectangular geometry allows wringing to other gage blocks for combination builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard rectangular gage block compatible with other Grade AS-1 and Grade AS-2 steel gage block sets using the same rectangular form factor for wringing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGage blocks are precision instruments and should be handled by qualified metrology or inspection personnel. Clean all mating surfaces thoroughly before wringing blocks together to prevent surface damage. Store blocks in a controlled-temperature environment to minimize thermal expansion effects on measurement accuracy. Never use gage blocks as general-purpose setup spacers where impact or clamping forces could damage the lapped surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize (Nominal)\u003c\/strong\u003e: 0.85000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy Grade\u003c\/strong\u003e: AS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification Standard\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630-33856\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692393333042,"sku":"630-33856","price":37.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da51329956664e589ff67c41f421f53f.jpg?v=1788297059","url":"https:\/\/voomisupply.com\/products\/value-collection-630-33856-steel-gage-block-0-85-in-grade-as-1","provider":"Voomi Supply","version":"1.0","type":"link"}
